Question

what happens to the particles in a substance as you raise the temperature? the particles gain more energy, causing them to move around more, spread out, and take up more volume. it depends on the substance; some substances will have particles that gain energy, and some substances have particles that will lose energy. the particles lose energy, causing them to slow down, come closer together, and take up less volume. the particles slowly lose energy until they stop moving altogether.

Explanation:

Based on the kinetic - theory of matter, when temperature is raised, the average kinetic energy of particles increases. This causes them to move more, spread out, and occupy more volume.

Answer:

The particles gain more energy, causing them to move around more, spread out, and take up more volume.
